Cells water containment
70-95%
Special properties due to hydrogen bonds
Cohesion and adhesion
Capillary action
water can flow against gravity
Surface tension
water can support more mass than other liquids
Cohesion
water interacting with water
Adhesion
water interacting with polar charged molecules
High Specific Heat
heat amount gained or lost to change by 1 degree C
High Heat of Vaporization
Heat requirement for 1 gram of water to go from liquid to gas
Evaporative Cooling
hottest molecules evaporate leaving cool molecules behind
Density of Ice
ice floats due to hydrogen bond creating crystal lattice (creating space); 4 degrees C is most dense
Polar Solvent
dissolves many substances and allows chemical reactions
Solvent
liquid which solute is dissolved in
Aqueous
H20 Solvent
Hydrophobic
not attracted to water
Hydrophillic
water loving polar/charged
pH
-log[H+]
Acid
substances have more protons
Base
substances have less protons
Buffers
regulate proton concentration, changes in solution
